    摘要: Communication with adapters of a computing environment is facilitated. Control instructions specifically designed for communicating data to and from adapters are provided to facilitate the communication. The instructions explicitly target the adapters. Information provided in an instruction is used to steer the instruction to an appropriate location within the adapter, such as a Peripheral Component Interconnect (PCI) or Peripheral Component Interconnect Express (PCIe) adapter.

    摘要: An Infiniband flow control scheme disables credit based flow control so that transmission distances can be extended. An Infiniband credit based flow control suffers from round trip time lag that slows transmission rates. Disabling Infiniband credit based flow control enables back to back packet transmission because credit counts are ignored. Nonetheless, packets can be lost due to overruns in a receive buffer, therefore, packet drop detection mechanisms are employed so that the Infiniband receiver can send requests to the Infiniband transmitter to temporarily slow its Infiniband transmission rate.

    摘要: A low latency multicasting receive and send apparatus and method comprising low latency receive and send queues. In an InfiniBand® network each destination group of nodes (recipients) is identified by a unique Global ID (GID)+Local ID (LID). Each node whose ports are part of a multicast group identify themselves via a LID which identifies participating ports. When a switch receives such a multicast packet with a multicast LID in the packet's DLID field it replicates the packet to each of the designated ports. Each destination adapter at a receiving node receives the multicast packet and distributes copies of the packet to QPs in the host system that are registered for the multicast address.

    摘要: A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualized channel adapter. Otherwise, when the destination is not supported for routing via hardware, the virtualized channel adapter is operable to route the communication via firmware to a virtual port of the virtualized channel adapter. A corresponding method and a recording medium having information recorded thereon for performing such method are also provided herein.
